Fig. 8. Strong anion exchange chromatography of the laminarinase from C. destructor on a Bio-Rad Mono-Q column. Combined and concentrated fractions 60–62 from the HIC described in Fig. 6 and containing laminarinase 1 derived from the midgut gland of C. destructor were loaded onto the Mono-Q column. Protein concentration (mg protein ml^–1, ) and laminarinase activity (µmol reducing sugars produced min^–1 ml^–1, ) in the collected fractions.
